rolled sheets of hexagonal carbon structures in the "chicken wire"-like form; can be either semiconducting or metallic; due to the ultra-small size should provide, in theory, faster switching than any of today's semiconductor structure.

Definition

carbon nanotube

typically a rolled sheets of hexagonal carbon structures in the "chicken wire"-like form; due to ultra-small diameter (sub-100 nm) should provide, in theory, faster switching than any of today's semiconductor structures; single nanotube transistor (FET)is considered for switching applications in post-CMOS era; depending on structure can also display metallic properties.

graphene,

a two-demensional part of the three-dimensional graphite, i.e. a single atom thick planar sheet of carbon bonded in a specific fashion; sometime referred to as "carbon sheet"; rolled into a cylinder, graphene will form a single-walled carbon nanotube; potentially usefull in the fabrication electronic devices including ballistic transistor.
